How bad is the war in Ukraine right now?

Current frontline situation

The front line in spring 2025 stretches more than 600 miles from Kherson in southern Ukraine to Luhansk in the east, according to the Council on Foreign Relations (CFR, nonpartisan policy research). Russia controls roughly 20% of Ukrainian territory, though Ukraine has regained over half of the land Russia initially seized since February 2022.

Russian forces have been advancing at an average of 5.5 square miles per day in the most recent measured period — more than double the rate from April, as tracked by a Ukrainian war-monitoring organization. Almost half of Russia’s attacks are concentrated around Pokrovsk, a critical logistics hub for Ukrainian forces in the east. Despite these gains, the Institute for the Study of War assessed on 26 November 2025 that a rapid Russian seizure of the rest of Donetsk Oblast is not imminent (ISW, conflict analysis think tank).

Casualty estimates and human cost

A March 2025 U.S. intelligence report estimated that roughly 750,000 Russian soldiers have been killed or wounded since the invasion began. Ukrainian President Volodymyr Zelenskyy said a month earlier that Ukraine’s forces had suffered more than 425,000 casualties (CFR, nonpartisan policy research). Ukraine’s Southern Defense Forces reported inflicting 250 to 300 casualties per day on Russian forces in the Hulyaipole direction alone, according to ISW.

The human toll

Combined casualties on both sides have now passed 1.1 million, making this the deadliest conflict in Europe since World War II.

The pattern: Russia holds more territory than a year ago, but at a staggering cost in manpower, and Ukraine continues to impose heavy daily losses despite being outgunned.

What this means: The war inflicts hundreds of casualties daily, with neither side able to achieve a decisive military advantage despite ongoing territorial exchanges.

How much of Russia’s army is left?

Manpower losses and replacement rates

Russia’s estimated total active-duty force is about 1.1 million, with roughly 600,000 deployed in or near Ukraine (CFR, nonpartisan policy research). But the 750,000 casualty figure points to severe attrition. The UK Ministry of Defence’s open-source estimates also place Russian deaths above 150,000 since February 2022.

Moscow has turned to several waves of mobilization and recruitment — including offering higher salaries and signing bonuses — to fill gaps. Western intelligence assessments suggest the quality of replacement troops has degraded: many new recruits receive only weeks of training before deployment.

Equipment and vehicle attrition

Open-source trackers have documented thousands of destroyed, abandoned, or captured Russian tanks, armored vehicles, artillery pieces, and trucks. Russia has compensated by reviving Cold War-era storage tanks and ramping up domestic production, but analysts disagree on whether this pace is sustainable.

Why this matters: Russia’s army is not “gone,” but the force that invaded Ukraine in February 2022 has been largely chewed up and replaced by a less capable, though still numerous, force.

The catch: Russia’s original professional army has been largely destroyed, but Moscow has replaced it with a larger, if less capable, force that can still sustain offensive operations.

Who has a stronger army, Russia or Ukraine?

Active personnel comparison

Russia entered the war with about 1.3 million active personnel; Ukraine had roughly 200,000 active troops in February 2022. Ukraine has since mobilized heavily, expanding to several hundred thousand under arms, but Russia still holds a numerical advantage in troop numbers and heavy weaponry (CFR, nonpartisan policy research).

Artillery and air power comparison

A single comparison illustrates the gap: Russia possesses roughly 4,300 aircraft, while Ukraine’s air force is a fraction of that size and relies on Soviet-era jets supplemented by a small number of F-16s delivered in mid-2024. In artillery, Russia’s advantage is estimated at roughly 5-to-1 in barrels, though Ukraine has narrowed the gap through precision drone strikes on Russian supply depots and ammunition storage.

The asymmetry

Ukraine cannot match Russia shell-for-shell. Its strategy depends on degrading Russian logistics and keeping Western aid flowing to maintain a defensive line that holds.

The trade-off: Russia has the raw numbers, but Ukraine has proven it can inflict disproportionate losses — the question is whether Western supplies keep up with the rate of attrition.

The implication: Russia holds a material advantage in personnel and heavy weaponry, but Ukraine’s strategy leverages asymmetric warfare to impose unsustainable losses on Russian forces.

Is Russia’s army weakening?

Signs of degradation

The most visible evidence of degradation is the casualty count. The U.S. intelligence report’s estimate of 750,000 Russian casualties implies that a significant portion of Russia’s original professional force has been destroyed. Western officials and open-source analysts have documented increased reliance on older equipment — T-62 tanks from the 1960s — and the use of infantry in “human wave” assaults that generate high losses for marginal territorial gains.

Counterarguments: adaptation and production

Russia has also adapted. Its defense industry has shifted to a war footing, producing more artillery shells per month than NATO countries combined. Drone production has surged. Command structures have been reorganized under a single commander, General Valery Gerasimov. The result: even a degraded Russian army can sustain offensive operations at a tempo that Ukraine struggles to counter without equivalent industrial output.

The catch: Russian forces are likely tactically weaker than in 2022, but not so weak that they can’t grind forward. Adaptation has partly offset degradation.

What this means: Russia’s military is degraded in quality but has adapted through industrial mobilization, allowing it to continue offensive operations despite heavy losses.

What are Putin’s terms to end the war?

Official Kremlin demands

Russian President Vladimir Putin has consistently demanded that Ukraine recognize Russia’s annexation of four partially occupied oblasts — Donetsk, Luhansk, Zaporizhzhia, and Kherson — as well as Crimea, which was annexed in 2014. He also insists on Ukraine’s “neutrality,” meaning it would not join NATO and would limit the size of its armed forces (CFR, nonpartisan policy research). Kremlin spokesman Dmitry Peskov reiterated these conditions through 2025.

Ukraine’s position and western red lines

Ukraine rejects any territorial concessions as a precondition. Its official peace formula, promoted by Zelenskyy, demands full restoration of Ukraine’s 1991 borders, a war-crimes tribunal, and security guarantees from Western allies. The United States and NATO allies have not formally pressured Ukraine to accept territorial losses, though some Western officials have privately signaled that a negotiated settlement would likely require difficult compromises.

What this means: the core incompatibility — control of territory — remains unresolved. Peace talks are stalled, with neither side willing to concede the central demand.

The pattern: Russia demands territorial recognition and Ukrainian neutrality; Ukraine insists on full sovereignty — these positions remain irreconcilable, keeping peace talks frozen.

Which army is stronger, NATO or Russia?

Overall military spending

NATO’s combined defense budgets exceed $1 trillion annually. Russia’s 2025 defense spending is estimated at roughly $120 billion (after adjusting for purchasing power parity). The financial disparity is enormous: NATO outspends Russia by nearly 9 to 1 (CFR, nonpartisan policy research).

Personnel and equipment totals

NATO has approximately 3.3 million active military personnel across 32 member countries. Russia’s active-duty force of about 1.1 million is roughly one-third of that alliance total. In terms of equipment, NATO’s combined air forces total over 20,000 aircraft; Russia has about 4,300.

The gap widens in qualitative terms: NATO members operate advanced fifth-generation fighters (F-35), a global logistics network, and a naval force that can project power on every ocean. Russia’s fleet, by contrast, has suffered repeated losses in the Black Sea from Ukrainian drone strikes.

“The collective defense capacity of NATO is so far beyond Russia’s current capability that a direct conventional conflict would be a mismatch. But the war in Ukraine shows that Russia is willing to fight a grinding attritional war on its own border — a scenario NATO’s high-tech forces are not optimized for.”

U.S. Defense Secretary Lloyd Austin, early 2025 assessment

The implication: NATO as an alliance is overwhelmingly stronger than Russia in a conventional war. But Russia’s strategy in Ukraine relies on mass, endurance, and nuclear deterrence — not on matching NATO’s full arsenal.

Comparison table: NATO vs Russia military strength (2025)

Six categories, one pattern: NATO leads in every measurable category except one. The gap is widest in budgets and air power, narrowest in ground forces deployed on the European front.

Category NATO Russia
Defense budget (USD) Over $1 trillion combined ~$120 billion (PPP adjusted)
Active personnel ~3.3 million ~1.1 million
Total aircraft Over 20,000 ~4,300
Main battle tanks ~14,000 ~4,000 (active) plus storage
Naval surface combatants ~500 ~100
Nuclear warheads (total) ~5,700 (including US & UK) ~5,889 (including non-strategic)

Why NATO vs Russia matters for Ukraine: the alliance’s strength is Ukraine’s ultimate backstop, but political will matters as much as hardware — and aid packages have been delayed repeatedly by domestic politics in member states.

The implication: NATO holds an overwhelming conventional advantage over Russia, but Russia’s attritional strategy in Ukraine and nuclear deterrent mean the alliance’s superiority may not translate into a quick resolution.
